Strikingly red with a tender, velvety crumb, this classic Southern layer cake is a true showstopper. A hint of cocoa powder gives the sponge a subtle chocolate flavor that pairs perfectly with the rich, buttery ermine frosting. This traditional cooked-flour icing offers a silky-smooth texture that isn't overly sweet, letting the cake's flavor shine. It's a beautiful centerpiece for holidays, birthdays, or weekend gatherings.

Ingredients
2 ½ cups all-purpose flour
1 ½ cups sugar
2 tablespoons unsweetened baking cocoa
1 tablespoon baking powder
1 teaspoon salt
1 ½ cups vegetable oil
1 cup buttermilk
1 teaspoon vanilla
1 bottle (1 oz) red food color
2 eggs
½ cup all-purpose flour
1 ½ cups milk
1 ½ cups sugar
1 ½ cups butter, softened
1 tablespoon vanilla
Instructions
1Preheat the oven to 350°F. Coat the bottoms and sides of three 8-inch or 9-inch round cake pans with shortening, then dust lightly with flour. This prevents the delicate sponge from sticking.
2Combine 2 1/2 cups flour, 1 1/2 cups sugar, cocoa, baking powder, salt, oil, buttermilk, 1 teaspoon vanilla, red food coloring, and eggs in a large bowl. Mix on low speed for 30 seconds while scraping the sides. Increase the speed to medium and beat for 2 minutes. Divide the batter evenly among the prepared pans.
3Bake for 25 to 35 minutes, checking for doneness with a toothpick. Let the cakes rest in the pans for 10 minutes before transferring them to a wire rack to cool completely, about 1 hour. Don't rush the cooling process, as warm cakes will melt the frosting.
4Whisk 1/2 cup flour and the milk together in a medium saucepan until completely smooth. Cook over medium heat, stirring continuously, until the mixture is very thick. Constant stirring keeps lumps from forming in the frosting base.
5Remove the saucepan from the heat and let it cool for 10 minutes. In a separate large bowl, whip 1 1/2 cups sugar and the softened butter on medium speed until the mixture becomes light and airy.
6Add the cooled flour mixture to the butter mixture one tablespoon at a time, beating on high speed until completely smooth. Mix in 1 tablespoon vanilla. Spread 1 cup of the frosting between each cake layer, then frost the top and sides.
Notes
Storage: Keep the frosted cake covered in the refrigerator for up to 5 days. Let it sit at room temperature for 30 minutes before serving.
Cupcake variation: Line 24 muffin cups with paper liners and fill two-thirds full. Bake at 350°F for 20 to 22 minutes. Cool completely before frosting.
Frosting tip: Make sure the cooked flour and milk mixture is completely cool before adding it to the butter, or the frosting will melt and separate.
Ermine frosting: This traditional cooked-flour frosting is less sweet than standard American buttercream and perfectly complements the rich cake.
